4.3. Construction

Rather than copying files directly to the ramdisk, we can make
things easier by setting up a staging area. The staging area will give us
room to work without worrying about the space constraints of the ramdisk.
It will also provide a way to save our work and make it easier to enhance
the rootdisk in later phases of the project.

4.3.4. Copy additional libraries

Note the differences in the required libraries, as shown by the
ldd command, and the libraries present in the staging
area, as shown by the ls command, then copy any
missing libraries to the staging area.
